Hi. I fly exclusively in VR and are looking into upgrading my hardware. currently on a 2080ti with 32 GB ram and a i9 9900K processor.. The rig is about 3 years old and I do get the occasional CTD when flying airliners which I prefer. I am looking into a 3090 setup with all the bells and whistles …

Ok thanks. In what way does the Pre-Caching influence RAM? I thought that was stored in the Rolling Cache?

32Gb of RAM is fine, and your 2080Ti has (I think) 8 or 10 GB of VRAM. Your current rig will do for a long time yet. If you watch Task Manager you can see the sim uses less than 6 GB of VRAM. That’s the one to watch. When the GPU runs out of dedicated VRAM it starts swapping to disk, and that ca…

[image] Archer374: Ok thanks. In what way does the Pre-Caching influence RAM? I thought that was stored in the Rolling Cache? I doubt it, that wouldn’t do much to reduce the stuttering. But they haven’t said explicitly what it is AFAIK. Even on an SSD, loading from disk would probably be too…

More RAM usage would indeed be good. It’s always best to cache stuff in the fastest medium and there is nothing faster than RAM (apart from the CPU cache of course).

I run MSFS on Windows 10 Virtual Machine through KVM/VFIO/QEMU on a Linux host, with a Nvidia 2080 GPU passed through. I tested MSFS on different RAM configs even before SU5, from 16 to 24 to 32 GB. Even before SU5, the amount of RAM never seemed to be the bottleneck. When I ran it on a 16GB VM, MSF…

My understanding is that rolling cache is on disk, which contains photogrammery data that was streamed from Azure cloud. So ‘before and while’ you start flying, data needs to be fetched from Azure cloud. If you already flew there, this data is already in your rolling cache, then the game doesn’t n…

ah ok. Two different things then. Thanks

I have 64 GB of RAM. (i9-990K, Samsung 970 EVO Plus NVMe SSD) I have no problems with FS2020. 4K at OBj LOD = 9 and Terrain LOD = 9. Graphics are great with a GTX 1660 TI.

I upgraded from 32gb to 64gn during the era of the great stutters. The sim actually seemed more stable and I experienced fewer major stutters. Some major changes were made to the way the sim handles memory in SU5 so I rarely see it use anywhere near my max physical memory at present. However, I p…

Can you link to that tip? :slight_smile:

What and how does RAM impact performance in the sim_
